I. OVERVIEW

The Oregon Weatherization Assistance Program (WAP) Single Family/ Mobile

Home/Small Multi-family (< 25 units) Audit Protocol is a guidance document that

defines the required criteria for the development of an energy audit designed to justify the

cost effectiveness of energy efficient building retrofits under Oregon’s WAP. This

document specifically addresses the audit protocol for Single Family site built structures,

manufactured homes and small multi-family projects. Underlying this protocol are the

principles of transparency, consistency, and accountability: data contained in the audit

must be transparent in terms of methodology of collection and calculation; report content

must be consistent; and persons completing the audit must be accountable for their work

by adhering to protocol requirements, maintaining professional certifications, and

providing quality assurance measures.

A key objective of an energy audit is to identify feasible and relevant energy conservation

measures (measure) that qualify for funding under Oregon’s WAP. In addition to

identifying ways to reduce the energy burden, the audit process must also conduct

evaluation of the integrity of the building to identify any deficiencies that could result in

health and safety issues as defined by Oregon’s WAP.

The outcome of the site specific audit process is a report that identifies cost effective

weatherization measures based on the:

Location, climate zone, utility information and other relevant site information;

Building profile, configuration and existing energy systems;

Related health and safety checks and conditions;

Calculated savings-to-investment ratio (SIR) of each measure including

interactive effects of higher SIR measures (calculated in REM/Design™ ); and

Total calculated reduction in energy usage for the recommended measures

(calculated in REM/Design™).

The four main processes that constitute the Oregon WAP Single family/Manufactured

Home Small Multi-Family Audit Protocol standards include:

1. The on-site audit visit

2. The energy modeling and energy savings analysis

3. Report generation

4. The on-site final inspection

For energy audit purposes, OHCS considers single family buildings to be those

containing four dwelling units or less.


II. ON-SITE PROCESS

The purpose of the on-site visit is to collect all necessary information to conduct an

appropriate energy usage and health and safety analysis, including sufficient information

to complete an energy model. The intent is to evaluate building envelope, assess building

airflow, inventory HVAC and other energy systems equipment, identify ventilation

systems, and perform diagnostic testing.

The following process includes manufactured home, site built and small mutli-family

units. In most cases, the process is similar for all housing types. Where the process will

differentiate between housing types, the specific differences will be noted.

1. Auditor Conduct Standards and Minimum Credentials

All sub-grantees and their consultants shall conform to the OHCS contracts,

policies, and referenced standards.

Auditors and Inspectors conducting audits shall have the minimum skills,

credentials and experience detailed under section 2.20.1 of the Oregon USDOE

state plan. At a minimum, Auditors shall be capable of effectively performing the

following tasks:

o Energy modeling utilizing REM/Design™ software.

o Building assessment (identifying safety, code, durability and energy

systems issues).

o Diagnostic testing (Blower door, duct pressure testing, pressure

diagnostics etc.)

o Combustion appliance safety testing.

o Feasibility analysis for the installation of energy efficient building

improvements.

2. Scheduling the Site Visit and Tenant Notification

Notification of the client(s), whose home(s) will be reviewed during audit site

visit, will be the responsibility of sub-grantee, the property owner, or their

representative.

The Auditor shall schedule the site visit(s) with the designated person(s) at a time

that is convenient for the project contact person(s). The site visit should seek to

cause minimal disruption for the client.

3. Site Visit Preparation

To facilitate the on-site portion of the energy audit, it is recommended that the following

items be addressed prior to arrival.


Review the income verification to verify the client(s) is/are eligible to participate

in the weatherization program.

Review 12 months of prior utility bills, if available. (Including gas and electric) to

know annual utility cost by fuel type and seasonal variations.

Review existing mechanical equipment information as available.

Verify with contact that you will have access to all portions of the property.

Verify that wood burning equipment will not be in use on the day of the audit if

possible.

4. Site Visit Field procedures

The on-site energy audit shall be comprised of an in-person visit to the project by a

qualified Auditor to complete the following tasks:

4.1 Project Interview(s)

The Auditor shall interview at least one of the following designated person(s)

prior to or at the time of the site visit:

Building Occupant/Client

Owner or Owner Representative

The purpose of the interview(s) is to:

Discuss the structures energy performance.

Discuss occupant comfort, health and safety.

Discuss any behavioral or other factors affecting energy performance.

Address any other occupant questions or concerns.

The interview shall include questioning on site conditions and deferred

maintenance issues. If an occupant wishes their responses to remain confidential,

the Auditor shall respect those requests.

4.2 Safety and Code Observations During the Site Visit

Each site visit must address specific minimum health and safety checks. The

Health & Safety plan contained in the Oregon USDOE state plan, as well as the

Oregon Site Built and Mobile Home specifications, apply to this policy. Where

not referenced specifically, the following minimum health and safety checks shall

be conducted and recorded in the Energy Audit Report or supporting

documentation.

Note likelihood of lead presence based on age of building as relevant to

EPA & Oregon CCB RRP Rules.

Mold and Mildew Assessment per Exhibit 6 of the USDOE State plan.

Structural, electrical and mechanical systems visual inspections.

If a combustion appliance of any type is present, the following testing is

required as per Appendix D, Section V – 2 of the USDOE state plan:


o Ambient CO testing

o Worst case depressurization (excludes ranges and ovens)

o Draft testing (excludes fireplaces, woodstoves, pellet stoves and

sealed combustion appliances)

o Undiluted flue gas CO testing (excludes fireplaces, woodstoves,

pellet stoves)

4.3 Visual Inspection and Diagnostic Testing Protocols

The site visit shall include visual inspections and diagnostic testing of the building

envelope, HVAC and combustion appliances. Minimum visual and diagnostic

testing criteria are provided in the Oregon USDOE Health & Safety Plan and the

Oregon Site Built and Mobile Home Weatherization Specifications. These

standards provide the minimum required testing procedures for Combustion

Appliance Safety, Blower Door and Duct Leakage Testing. All testing, both pre

and post, must be documented on a diagnostic testing form. The form must be

signed and dated by the person doing the testing for both pre and post testing. An

overview of diagnostic testing protocols is listed below. For more detail refer to

the referenced documents.

Blower door testing: Pre and post blower door testing is required on all

single family and mobile home projects unless conditions prohibit. All

blower door tests must include zonal pressure testing of all spaces adjacent

to conditioned space. On multi-family projects it is allowable to test a

representative sample. See section 8.02 of the Oregon Site Built and

Mobile home weatherization specifications.

Duct leakage testing: Pre and post duct leakage testing is required on all

homes with forced air heating systems unless conditions prohibit. See

section 8.08 of the Oregon Site Built and Mobile Home weatherization

Specifications.

Ventilation airflow testing: All exhaust fans must have airflow measured if

possible. ASHRAE compliant fans must be tested post weatherization. See

section 9 of the Oregon Site Built and Mobile Home weatherization

Specifications.

Room pressure testing: Room to room pressure testing must be completed

on all homes when forced air heating is present. See appendix U of the

Oregon Site Built and Mobile Home weatherization Specifications.

all aspects of Appendix D of the USDOE state plan as well as specific testing

protocols contained in the Oregon Site Built Weatherization Specifications.

Health & Safety repairs do not have to be included in SIR calculations.


4.6 Energy Education

During the site visit both auditors and inspectors will provide basic client

education to the client. At the initial audit, the auditor provides the initial

information and the Inspector must provide additional energy education to

reinforce the information provided at the audit. Subgrantees are required to

provide client education that encourages households to reduce their home energy

needs. Each Subgrantee has the latitude to develop their own client education

program but they must provide at least the following.

Written information that describes energy saving behavioral adjustments

that will decrease the energy consumption of the household;

Discuss the importance of indoor air quality, the purpose and benefits of

the ASHRAE 62.2 requirement and the importance of using and

maintaining ventilation equipment.

Information in the use and maintenance of any equipment installed

including but not limited to, CO Alarms, furnaces and ventilation

equipment. This must be provided verbally as well as any

users/maintenance manuals must be provided to clients.

Any health and safety issues identified must be discussed with the client

and appropriate actions taken as stated in the Appendix D of the USDOE

H&S plan.

Discuss the benefits that can be expected of the weatherization

measures to be installed and how to maximize the effect of each measure.

4.7 On-Site Inspection

100% of all completed units must be inspected by the subgrantee. A thorough on-

site inspection and documentation of each dwelling unit including pre and post

weatherization blower door testing, pre and post duct blaster testing when a forced

air system is in use, pre and post health and safety testing results, ASHRAE

compliant fan flows measured and review of all installed measures for compliance

with the standards set forth in the Oregon Site Built and Mobile Home

Weatherization Specifications. Inspection results must be documented on an

inspection form listing all measures installed signed and dated by the inspector.

Diagnostic and H&S testing must be documented on a diagnostic testing form

signed and dated by the inspector.

Allowances are made for a representative sample of blower door test to be

completed on buildings with 5 or more units. See section 8.02 of the Oregon

Mobile Home and Site Built Weatherization Specifications.

OHCS QA inspectors will perform inspections of the installed weatherization

measures on a minimum of 5% percent of completed projects. These inspections

will be comprised of a statewide random sampling of the homes weatherized.

Diagnostic tests will be re-performed on a sampling of dwellings to ensure that

the tests are being properly conducted.


III. ENERGY MODELING AND ANALYSIS PROCESS

An energy model of the building’s pre and post-retrofit performance shall be completed

using initial inspection data and diagnostic data collected during the on-site visits.

REM/Design™ energy modeling is used to estimate annual energy consumption and

energy cost savings of most potential energy conservation measures for dwellings as

defined in Section III, 1.1. All energy and cost savings results from the REM/Design™

model must be verified against known conditions and usage profiles existing at the

residence. All REM/Design™ models must be trued to actual metered usage to the

greatest extent possible.

1. Energy Modeling Software Requirements:

The REM/Design™ energy modeling software platform has been approved by DOE for

use in the OR WAP program for single family, manufactured and small multifamily

dwellings. The energy audit software policy is provided below.

REM/Design™ Dwelling Criteria

As defined in the policy, REM/Design™ audit is to be used for the following

building types:

Single-family dwellings up to 4-plexes,

Manufactured homes, and

Low-rise multifamily buildings:

o Containing five to 25 dwelling units,

o Having 3 stories or fewer and,

o Where buildings containing 5 to 25 dwelling units are heated and

cooled independently.

The REM/Design™ energy audit process requires a physical inspection of the

home, specific diagnostic tests, and proper data input into the software program.

An energy profile of the existing home is compared to a set of improvements

recommended for installation. Each measure is then evaluated and a report is

generated with the cost-effectiveness of each measure listed by SIR (Savings to

Investment Ratio).

2. SIR Requirements

All measures must be interacted.

Mortgage discount rate must be set at 3.0

Measure costs modeled must include the cost of materials, labor and on-site

supervision.

Individual measures, except air sealing (see section 8), must have an SIR 1.0

or greater by themselves.

All cost effective measures, including air sealing costs, must have a grouped

SIR of 1.0 or greater.


3. User Defined Measures

REM/Design™ allows that users may define measures that are not included the existing

libraries. Any user defined entries must be reviewed for accuracy by a person certified by

OHCS in the use of REM/Design™. User defined entries must follow criteria listed in the

OHCS REM/Design™ Technical Policies.

Compliance in the use of user defined measures will be ensured though the monitoring

process. Projects will be randomly selected for the monitoring process. Agencies are

required to supply the REM/Design™ electronic files to be reviewed to OHCS for all

aspects of modeling including user defined measures.

4. Single family (2-4 UNIT), Small Multi-family Modeling Considerations

These considerations apply to all small multi-family dwellings as well as any single-

family dwelling composed of more than one individual unit.

Parameter Requirement

REM/Design™ Input Mode Detailed

Housing Type Multi-family whole building

Walls Account for all walls adjacent to

unconditioned space such as

garages or outdoors.

(Do not model walls between units)

Floors Account for all floors adjacent to

unconditioned space such as

garages, ground, crawlspace, etc. Do

not include floors adjacent

to other apartments or common areas.

Ceilings Account for all ceilings adjacent to

unconditioned space such as attics or

vaulted ceilings adjacent to outdoors.

Do not include any ceilings adjacent to

other apartments or conditioned space.

Number of Bedrooms Include all bedrooms in the building

Mechanical Equipment Each model of similar equipment types

must be accounted for. Instances of

similar models may be input as

increases quantities of that model.


As seen in the specifications above, all interior walls and ceilings are omitted. When

inputting the number of bedrooms the model must account for the TOTAL number of

bedrooms in the entire building, not just the number of bedrooms per dwelling.

The model must also account for all mechanical equipment in the building. When

inputting mechanical equipment each piece can be manually created or if all pieces of

equipment are identical the number of units can be increased on the “Mechanical

Equipment Properties Summary” page in REM/Design™.

5. Mobile Home Special Considerations

Although REM/Design™ allows for modeling shell measures using “quick fill mobile

home”, it is allowable and encouraged to model mobile home shell measures using “quick

fill site built”.

6. Mechanical Equipment Properties

Whenever possible, actual equipment information indicated on the mechanical

equipment, or made available by manufacturer or professional web site, are to be input as

existing properties, e.g., AFUE, SEER and EF, for the furnace, air conditioner, and hot

water heater, respectively. Further, a performance adjustment of 100% (functions as new)

is used when modeling mechanical equipment for the building. Reducing the performance

adjustment is only allowed when actual energy usage justifies a reduction and the

equipment is in need of repair. Any time a performance adjustment is used, the equipment

must be repaired and the cost justified with an SIR of 1.0 or better. Default properties are

to be used ONLY when values are unavailable from equipment nameplates, equipment

tags, etc. Using the REM/Design™ energy audit for change out of mechanical equipment

is strictly for “efficiency” purposes. However, before a faulty furnace may be replaced as

a health and safety measure, the existing furnace to new furnace upgrade must be proven

non-cost effective with an SIR of less than 1.0.

7. Duct System

The duct system may be sealed and insulated during weatherization. Energy savings must

be based on leakage measured through the use of the Duct Blaster. Both a pre and post

test must be performed when duct sealing is completed. If the final duct leakage reduction

does not achieve 75% of the targeted reduction, the post duct leakage rate must be input

into the REM/Design™ model and an updated SIR produced.

Example: Pre leakage 300 cfm

Estimated Post leakage 100 cfm

Targeted reduction 200 cfm

200 cfm x 75% = 150 cfm minimum reduction is required.


8. Air Infiltration

The building envelope must be sealed during weatherization. Air infiltration, as an

individual conservation measure, is not required to have an SIR of 1.0 or better. However,

when all cost effective measures are packaged together with the infiltration measure, the

overall job cost must have a SIR of 1.0 or greater.

Energy savings for air infiltration in Manufactured and single family homes must be

based on actual measured flow using a blower door. Both a pre and post weatherization

blower door test must be completed. If the final blower door results do not achieve 75%

of the targeted reduction, the post blower door measured flow must be input into the

REM/Design™ model and an updated grouped SIR produced.

Example: Pre Blower door 2000 cfm

Estimated post blower door 1500 cfm

Targeted reduction 500 cfm

500 cfm x 75% = 375 cfm minimum reduction is required.

As Multi-family buildings present difficulties and accurately applying blower door results

due to leakage between units, it is allowable to utilize a visual inspection to determine a

user’s estimate in the REM/Design™ model. A reasonable reduction in infiltration based

on the auditors experience may be used to determine energy savings.

9. Model Calibration:

The energy model for all buildings shall, when possible, be calibrated to actual utility

billing data. Modeled baseline energy consumption shall be calibrated to monthly utility

bills for a minimum of twelve months when billing data is available. The intent is to

qualify the energy model by demonstrating similarity to the metered energy usage over a

12 month time frame.

1. The energy model estimates of electricity and natural gas should calibrate as close

as possible to actual annual energy consumption.

2. Baseload and heating load ratios shall be calculated using the OHCS utility

consumption analysis spreadsheet or other calculator as approved by OHCS.

3. Typical Meteorological Year (TMY) 30 year average weather data must be used

in energy modeling.

4. In the event that a building is served by more than one meter, the bills for those

meters shall be aggregated and the consumption calculated for the building as a

whole.

10. Incidental Repairs

Incidental repairs necessary for the effective performance or preservation of

weatherization materials are allowed. When a repair activity is a component of an

energy efficiency measure that is being installed then the installation and materials are

part of the efficiency measure and are classified as incidental repair. The cost of


incidental repairs must be included in the cost of the package of measures. The entire

package of measures installed on a project, including incidental repair costs, must be

cost justified with an SIR of 1.0 or better. See the Oregon USDOE State plan

Appendix D Section VIII – 1 for details.

11. Measure Buy Down

In the event that non-federal financial resources are leveraged to buy down a

particular measure, the following criteria must be met:

1) The SIR of the discounted measure must be 1.0 or greater when SIR is

calculated with only the WAP funds contribution.

2) The file must contain a funding summary sheet clearly identifying which

measures needed to be discounted using non-WAP funds, the type of funding

used and the amount of funds necessary to accomplish the buy-down.

3) Discounted measures may not be installed before non-discounted measures and

are only to be installed when all other available cost effective measures not

requiring buy-down have been installed. In no case shall measures with higher

SIRs be skipped or “leapfrogged” for measures with lower SIRs.

4) The cost effective portion of measures may be calculated by:

1. by adjusting the cost entered in REM/Design™ ™ until an SIR or 1.0 is

achieved or;

2. Entering the full measure cost into REM/Design™ and subtracting the

present value from the full cost to determine the cost effective portion.

Note: When using this method, when creating the grouped report, only the

cost effective portion should be included.

12. Utility Rates:

Actual utility rates in use at the time of the computer modeling of the project must be

used. Metered utilities (electric & natural gas) must include all rate tiers as well as any

monthly service charges. Metered utility rates must be updated, at minimum, annually.

For Non-metered fuel sources such as propane, wood, pellets or fuel oil local rates at the

time of the energy audit must be used.

13. Report Generation

The following Reports must be generated and included in the building file:

Improvement analysis Reports showing:

o Measures and SIR’s listed individually.

o All cost effective measures as well as air infiltration and any incidental

repair costs grouped for an overall SIR.

Fuel summary report

Performance summary report: A two building report comparing the improved

building to the unimproved building.


14. Measures Considered
